While Mississippi considers embracing more traffic light cameras, a few folks in Georgia are seeking a ban in their state. From the AJC:
Georgia legalized the cameras six years ago to improve safety, but several state lawmakers want to ban them across the state. They say the cameras are unconstitutional and are causing fender-benders.
“In the Constitution, you have the right to confront your accusers. And you cannot cross-examine a camera,” said state Rep. Bobby Franklin (R-Marietta). “And that is not even going into the public safety side of it, where you have numerous rear-end collisions where people are trying to avoid getting tickets.”
You might not be able to cross-examine a camera, but you should be able to challenge the algorithm, the mechanical/electrical operation of the system, and the timing of the traffic lights.
